Abstract Magnetic properties of the synthesized poly(N-perfluorophenylpyrrole) were studied. The synthesized polymer dissolves in common organic solvents. By the zero-field cooling-field cooling method (ZFC-FC) we found that at low temperatures (Tba state with prevailing ferromagnetism. The synthesized polymer retained ferromagnetism even at 300 K. The anomalous magnetic behavior was explained in terms of spin-spin interaction of triplet polarons. As can be seen from the calculated spin density of SOMO and SOMO 1 such a state arise as a consequence of 1-D spin interactions of polarons. Based on the calculated and visualized spin density (SOMO) on the polymer chain such interactions can be explained by the theory of flat-band-ferromagnetism.

Two new N-functionalized pyrrole-based organic dyes were designed and synthesized for dye-sensitized solar cells. In addition to the normal acceptor of cyanoacetic acid moieties, another electron-withdrawing group, pentafluorophenyl or cyanophenyl one, wa

Reactions of N-pyrrolylpotassium with fluorinated electrophiles yielded N-substituted pyrroles containing polyfluoroalkyl, polyfluoroalkenyl, polyfluoroalkylsulfonyl, and polyfluoroaryl substituents. N-Polyfluoro- substituted pyrroles did not isomerize at ≥100°C; they were found to be reactive in [4+2] cycloaddition reactions with perfluorobut-2-yne.

We present 1-pentafluorophenyl-1H-pyrrole and some of its electrophilic substitution reactions: formylation and acetylations. The 2-substituted products formed in these reactions are selectively and in high yield converted into 3-substituted products by treatment with trifluoromethanesulfonic acid. A general synthesis of 3-acylpyrroles was developed by the trifluoromethanesulfonic acid-mediated rearrangement of the corresponding 2-acylpyrroles.
